I still don't know the humanoid, though.

I don't see anything on the wiki for the humanoid. I'd think, given context, that it'd be an OS.

The wiki has what appears to be a slot reserved for DragonflyBSD on the Techno-Mage page, so there's a corresponding character in the comic, but if there was an image ever made, it's not present there.

From wiki humanoids:

• Based on coloration and style, it's not Girl.

• It's not Fosschild.

• It's not Nine.

As best I can tell, pmjv uses color pretty consistently to identify characters, so I don't think that it's some differently-colored variant of another character.

I don't see another character with black hair and blue-green skin in any recent comics.

The character was not present in "emoji":

...which is the most-recent comic I see that also has the above OpenBSD pufferfish and FreeBSD demon. Plus an anthropomorphic fox that I'd guess is maybe Xenia, Tux's trans+furry counterpart personification of Linux, though I don't see the sense in that, Spirit of the Machine from the wiki, the penguin that I assume is Tux, Glenda for Plan9 -- thanks, @pieguy@lemmy.sdf.org -- Girl, and an insect that I can't identify.

EDIT: The red insect in "emoji" was also present in "THE USUSAL MAGES", which is an allusion to the photo lineup at the beginning of The Usual Suspects, though doesn't help me out much here. Both comics apparently have users here trying to figure out what characters represent.

EDIT2: I was gonna say that the comic needs a wiki to explain things, but it has a wiki. I think that the comic's wiki needs a wiki to explain things...

EDIT3: The penguin is Penguin.
